Kev tiv thaiv electrostatic yog qhov yuav tsum tau-paub! HBM vs. MM: Yuav ua li cas kuaj qhov sib txawv hluav taws xob Shocks ntawm tib neeg lub cev thiab tshuab?

Kev tiv thaiv electrostatic yog qhov yuav tsum tau-paub! HBM vs. MM: "Yuav ua li cas ntsuas qhov sib txawv "Electric Shocks" ntawm tib neeg lub cev thiab tshuab?

Nyob rau hauv lub ntiaj teb niaj hnub no uas cov khoom siv hluav taws xob nyob txhua qhov chaw, electrostatic paug (ESD) zoo li qhov tsis pom "killer" uas tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob tsis zoo txhua lub sijhawm. Txhawm rau soj ntsuam thiab txhim kho ESD kev tiv thaiv muaj peev xwm (ESD Immunity) ntawm cov khoom, cov koom haum thoob ntiaj teb tau txiav txim siab ntau yam qauv ESD. Ntawm lawv, covTib neeg Lub Cev Qauv (HBM)thiab covTshuab Model (MM)yog ob qho uas feem ntau siv thiab tseem ceeb tshaj plaws.

Raws li tus kws tshaj lij EMC cov khoom lag luam, Shanghai Sosin Electronics Co., Ltd nkag siab tag nrho tias qhov sib txawv ntawm ob tus qauv no yog qhov tseem ceeb rau kev xaiv cov cuab yeej ntsuas tsim nyog thiab tsim cov tswv yim tiv thaiv zoo. Hnub no, peb yuav saib cov ncauj lus kom ntxaws txog HBM thiab MM.

1. Simulation scenarios: Leej twg yog "tso tawm"?

• HBM (Human Body Model):

Yam khoom simulation: Cov txheej txheem tso tawm thaum tib neeg lub cev raug them rau cov khoom siv hluav taws xob lossis cov khoom siv. Qhov no yog qhov feem ntau ntawm cov xwm txheej ESD. Piv txwv li, thaum tus neeg teb xov tooj txhais tes kov lub cuab yeej interface lossis PCB tus pin.

Cov yam ntxwv tseem ceeb: Nws simulates qhov paug tawm ntawm tib neeg lub cev (kwv yees li 100pF capacitance) los ntawm qee qhov tsis kam (kwv yees li 1.5kΩ) rau DUT / EU. Qhov tawm tam sim no waveform kuj qeeb (nce lub sij hawm ntawm 2-10ns, ntev li ntawm 100-200ns), nrog lub zog qis tab sis muaj ntau dua.

• MM (Machine Model):

Cov khoom siv simulation: Cov txheej txheem tso tawm thaum lub cuab yeej hlau lossis cov cuab yeej hluav taws xob tuaj yeem cuam tshuam nrog cov khoom siv hluav taws xob lossis cov khoom siv. Piv txwv li, hlau fixtures, mechanical / robotic caj npab, los yog cov cuab yeej nyob (xws li ib tug ungrounded soldering hlau taub) ntawm ib tug automated ntau lawm kab uas tuaj rau hauv kev sib cuag nrog cov khoom.

Cov yam ntxwv tseem ceeb: Nws simulates qhov tso tawm ntawm qhov qis -impedance metallic khoom (nrog rau qhov muaj peev xwm ntawm kwv yees li 200pF) rau qhov kev xeem dhau los ntawm qhov tsis tshua muaj me me lossis txawm tias qhov tsis zoo (<10Ω). The discharge current waveform is very fast and has a high peak current (rise time <1ns, short duration but with a significant current spike), with energy concentrated in an instant and greater destructive power. MM is considered a more severe test than HBM.

2. Qhov sib txawv tseem ceeb: HBM vs. MM

3. Daim ntawv thov scenario: Vim li cas thiaj yuav tsum paub qhov txawv ntawm qhov kev xeem?

Kev nkag siab txog qhov sib txawv ntawm HBM thiab MM ncaj qha txiav txim siab qhov tseem ceeb ntawm kev sim cov tswv yim thiab cov qauv kev tiv thaiv:

• Kev siv dav ntawm HBM kuaj:

Cheebtsam- kev xeem theem:ESD (electrostatic paug) cov qib tsis kam (xws li Chav Kawm 1A, 1B, 1C, 2, 3A, 3B) ntawm cov khoom siv semiconductor xws li chips, diodes, thiab transistors feem ntau yog raws li HBM tus qauv (xws li JS-001). Qhov no yog lub hauv paus rau kev ua kom muaj sia nyob ntawm cov khoom siv thaum tsim khoom, sib dhos, kev thauj mus los, thiab kev siv (tib neeg sib cuag).

Board-level/System-level Reference:Thaum IEC 61000-4-2 tseem yog tus qauv kub rau kev ntsuas kev tiv thaiv qib ESD (simulating huab cua / kev sib chwv tawm uas nyob ze rau tib neeg lub cev), HBM cov txiaj ntsig tseem muaj txiaj ntsig tseem ceeb rau kev nkag siab txog cov cuab yeej cuam tshuam thiab cov ntsiab lus tsis muaj zog ntawm cov khoom tseem ceeb.

Cov khoom siv hluav taws xob thiab kev sib txuas lus:Lub ntsiab ESD kev hem thawj los ntawm cov khoom no los ntawm tib neeg kev sib cuag. Kev ntsuam xyuas HBM yog tus yuam sij rau kev ntsuas lawv qhov kev ntseeg tau.

• Tus nqi tshwj xeeb ntawm MM xeem:
• High -Kev Tshawb Fawb Txog Kev Tshawb Fawb:Rau qee yam khoom uas muaj kev nkag siab zoo rau ESD (xws li qee lub zog MOSFETs thiab cov khoom siv RF tshwj xeeb), txawm tias lawv dhau qhov kev xeem HBM, lawv tseem yuav "tua tam sim" los ntawm cov cuab yeej hlau thaum lub sijhawm tsim khoom. Kev xeem MM (lossis ntau dua niaj hnub CDM, IEC 61000-4-2) yog ib qho tseem ceeb los xyuas seb lawv puas tuaj yeem tiv taus qhov kev sim hnyav ntawm qhov chaw tsim khoom siv hluav taws xob.
• Kev lag luam tshwj xeeb / hnyav ib puag ncig:Hauv cov khoom siv hluav taws xob uas siv hluav taws xob siab heev thiab kev tswj hwm kev lag luam, lossis hauv thaj chaw uas muaj kev ntseeg siab heev (xws li aerospace), kev ntsuas cov cuab yeej tiv thaiv rau hlau qhov chaw ESD (MM lossis CDM) yog ib kauj ruam tseem ceeb.
• Kev tswj cov txheej txheem ntau lawm:Kev nkag siab txog MM kev hem thawj ua rau kev siv cov kev tiv thaiv ESD nruj dua ntawm cov kab ntau lawm, xws li kev siv cov cuab yeej siv hauv av, kev siv cov kiv cua ion, thiab lwm yam.
